Description

Technical Field

[0001] This utility model relates to the field of material drying technology, and in particular to a material rotary drying device. Background Technology

[0002] Rotary drying, also known as drum drying, consists of a long, slightly tilted, rotating drum. Due to its large processing capacity and high operational safety, rotary drying is often used for drying granular materials with low moisture content. However, in existing rotary drying devices, air typically enters directly into the drying drum during operation, easily contaminating the raw materials and reducing their quality. Therefore, those skilled in the art provide a rotary drying device to address the problems mentioned in the background section. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a material rotary drying device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A material rotary drying device includes a fixed base, with an inlet pipe and an outlet pipe rotatably connected between the inner walls of the two sides of the fixed base, and a drying cylinder fixedly connected between the inlet pipe and the outlet pipe. Two symmetrically arranged fixed sleeves are fixedly connected to the inner circumference of the drying cylinder, and a heating wire is fixedly connected inside each fixed sleeve. One end of the outlet pipe is rotatably connected to a rotating sleeve. A fan is fixedly installed on one side of the fixed base, and an exhaust pipe is fixedly connected to the exhaust end of the fan. The exhaust pipe is fixedly connected to the rotating sleeve.

[0006] An air inlet sleeve is fixedly connected to the end of the air inlet pipe away from the drying cylinder. The air inlet sleeve has multiple through-holes around its circumference, and a dust cover is fixedly connected to the circumference of the air inlet sleeve.

[0007] As a further embodiment of this utility model, both ends of the drying cylinder are fixed with end caps by bolts.

[0008] As a further embodiment of this utility model, a mounting base is fixedly connected to the top of the fixed base, and a swing rod is rotatably connected inside the mounting base. A brush plate is fixedly connected to one end of the swing rod, and the brush plate is used in conjunction with the dust cover.

[0009] As a further embodiment of this utility model, a through screw is threaded onto one side of the mounting base, and the screw abuts against the swing rod.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0024] Reference Figures 1-4 A material rotary drying device includes a fixed base 1. An air inlet pipe 2 and an air outlet pipe 4 are rotatably connected between the inner walls of the two sides of the fixed base 1. A drying cylinder 5 is fixedly connected between the air inlet pipe 2 and the air outlet pipe 4. Two symmetrically arranged fixed sleeves 20 are fixedly connected to the inner circumference of the drying cylinder 5. A heating wire 22 is fixedly connected inside each fixed sleeve 20. One end of the air outlet pipe 4 is rotatably connected to a rotating sleeve 10. A fan 12 is fixedly installed on one side of the fixed base 1. The exhaust end of the fan 12 is fixedly connected to an exhaust pipe 11, which is fixedly connected to the rotating sleeve 10.

[0025] An air inlet sleeve 3 is fixedly connected to the end of the air inlet pipe 2 away from the drying cylinder 5. Multiple through-holes 13 are opened on the circumference of the air inlet sleeve 3. A dust cover 14 is fixedly connected to the circumference of the air inlet sleeve 3. After the fan 12 is started, it draws out the humid air in the drying cylinder 5. The outside air enters the drying cylinder 5 after being filtered by the dust cover 14, thereby improving the drying efficiency and preventing impurities and dust in the air from entering the drying cylinder 5.

[0026] In this utility model, both ends of the drying cylinder 5 are fixed with end caps 6 by bolts, and opening the end caps 6 makes it convenient for people to feed materials.

[0027] It should be noted that the top of the fixed base 1 is fixedly connected to the mounting base 16, and the mounting base 16 is rotatably connected to the swing rod 17. One end of the swing rod 17 is fixedly connected to the brush plate 15. The brush plate 15 is used in conjunction with the dust cover 14. The brush plate 15 contacts the dust cover 14 and cleans the dust cover 14 to prevent the dust cover 14 from becoming clogged.

[0028] In particular, a through screw 18 is threaded onto one side of the mounting base 16. The screw 18 abuts against the swing rod 17. After rotating the screw 18, the swing rod 17 is lifted by the screw 18, so that the brush plate 15 is separated from the dust cover 14, thus avoiding the brush plate 15 from contacting the dust cover 14 for a long time and improving the flexibility of use.

[0029] In this utility model, a motor 7 is fixedly connected to one side of the fixed base 1. One end of the output shaft of the motor 7 is fixedly connected to a pulley 8 on the circumference of the air inlet pipe 2. The two pulleys 8 are connected by belt drive. The motor 7 drives the air inlet pipe 2 to rotate through the pulleys 8. The air inlet pipe 2 drives the drying cylinder 5 to rotate. The raw material is turned over in the drying cylinder 5 and heated by the heating wire 22, thereby drying the material.

[0030] It should be noted that a protective door 9 is hinged to one side of the fixed base 1, and the protective door 9 protects the staff.

[0031] In particular, multiple baffle rings 19 are fixedly connected to the inner circumference of the drying cylinder 5. The baffle rings 19 increase the dispersion of the raw materials and improve the drying effect.

[0032] In this invention, a filter screen 21 is fixedly connected to one end of both the air inlet pipe 2 and the air outlet pipe 4. The filter screen 21 prevents raw materials from entering the air inlet pipe 2 and the air outlet pipe 4.

[0033] Working principle: In use, remove the end cap 6, then put the raw material to be dried into the drying cylinder 5. Then start the heating wire 22, motor 7, and fan 12. First, the motor 7 drives the air inlet pipe 2 to rotate through the pulley 8. The air inlet pipe 2 drives the drying cylinder 5 to rotate. The raw material tumbles in the drying cylinder 5 and is heated by the heating wire 22 to dry the material. After the fan 12 is started, it draws the humid air from the drying cylinder 5. The outside air enters the drying cylinder 5 after being filtered by the dust cover 14, thereby improving the drying efficiency and preventing impurities and dust in the air from entering the drying cylinder 5. At the same time, the brush plate 15 contacts the dust cover 14 to clean the dust cover 14 and prevent it from becoming clogged. After rotating the screw 18, the screw 18 lifts the swing rod 17, causing the brush plate 15 to disengage from the dust cover 14, preventing the brush plate 15 from being in contact with the dust cover 14 for a long time and improving the flexibility of use.

[0034] In this application, the structures and connections not described in detail are all prior art, and their structures and principles are well known, so they will not be described in detail here.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
